[0016] Embodiments of the disclosure provide a method and an apparatus for processing a channel state information (CSI) report configuration, a communication device, a communication system, and a storage medium.

[0017] In a first aspect, embodiments of the disclosure provide a method for processing a CSI report configuration. The method includes: sending, by a network device, a media access control (MAC) control element (CE) to a terminal, in which the MAC CE includes a first MAC CE, the first MAC CE carries first information, the first information indicates activation or deactivation of a sub-configuration of the CSI report configuration.

[0018] In the above embodiment, the network device sends the first MAC CE to the terminal and uses the first information in the first MAC CE to indicate the activation or deactivation of the sub-configuration of the CSI report configuration, thus realizing activation or deactivation based on the sub-configuration, and realizing activation or deactivation at a finer granularity than the CSI report configuration, which may reduce measurement power consumption of the terminal and save bit overhead.

[0019] In combination with some embodiments of the first aspect, in some embodiments, the first MAC CE includes: at least one first-type bit, indicating activation or deactivation of the sub-configuration.

[0020] In the above embodiment, the first MAC CE carries the at least one first-type bit. On the one hand, reporting of a CSI report of the terminal is activated by utilizing the first MAC CE. On the other hand, activation or deactivation of the sub-configuration is indicated by the at least one first-type bit in the first MAC CE, to realize activation or deactivation based on the sub-configuration.

[0021] In combination with some embodiments of the first aspect, in some embodiments, the first MAC CE further includes: at least one second-type bit, indicating activation or deactivation of the CSI report configuration; in which the at least one first-type bit specifically indicates activation or deactivation of a sub-configuration in an activated CSI report configuration.

[0022] In the above embodiment, the first MAC CE further includes the at least one second-type bit for indicating activation or deactivation of the CSI report configuration. The at least one first-type bit and the at least one second-type bit may indicate at least one activated CSI report configuration and the activation or deactivation of the sub-configuration in each activated CSI report configuration, such that the terminal may more accurately acquire the CSI report configuration and the specific sub-configuration adopted by the CSI report to be reported, which may reduce the measurement power consumption of the terminal, and save bit overhead.

[0023] In combination with some embodiments of the first aspect, in some embodiments, the first MAC CE includes: a third-type bit, in which the third-type bit indicates that the MAC CE is the first MAC CE in a case that the third-type bit is configured with a first bit value.

[0024] In the above embodiment, the first MAC CE further carries the third-type bit, and different bit values of the third-type bit are used to indicate the type of the MAC CE, such that, the terminal further obtains the activation or deactivation of the sub-configuration indicated by the first MAC CE after determining that the MAC CE is the first MAC CE based on the bit value of the third-type bit in the received MAC CE.

[0025] In combination with some embodiments of the first aspect, in some embodiments, the MAC CE further includes a second MAC CE. A second bit value of the third-type bit indicates that the MAC CE is the second MAC CE, and the second MAC CE indicates activation or deactivation of the CSI report configuration.

[0026] In the above embodiment, the network device may further send the second MAC CE to the terminal for indicating the activation or deactivation of the CSI report configuration. The second MAC CE further carries the third-type bit. Different bit values of the third-type bit are used to distinguish the first MAC CE and the second MAC CE, such that the terminal may realize the activate or deactivate of the CSI report configuration at different granularities according to different types of the received MAC CE.

[0027] In combination with some embodiments of the first aspect, in some embodiments, the at least one first-type bit is a bitmap, in which one bit in the bitmap indicates activation or deactivation of one sub-configurations; or the at least one first-type bit is joint indication information, in which a sequence value of the at least one first-type bit indicates a combination relationship of activation or deactivation of a plurality of sub-configurations, and the sequence value is determined based on at least one bit value of the at least one first-type bit.

[0028] In the above embodiment, the at least one first-type bit may indicate the activation or deactivation of at least one sub-configuration in the CSI report configuration through the bitmap, thus effectively reducing a decoding complexity of the at least one first-type bit in the first MAC CE by utilizing a correspondence between at least one bit in the bitmap and the at least one sub-configuration. Or, the at least one first-type bit may indicate the activation or deactivation of the at least one sub-configuration in the CSI report configuration through the joint indication information, thereby utilizing a smaller number of first-type bits to indicate a combination relationship of activation or deactivation of more sub-configurations, which may effectively reduce the number of bits occupied by the first MAC CE.

[0029] In combination with some embodiments of the first aspect, in some embodiments, the at least one first-type bit and the at least one second-type bit are located in different octets of the first MAC CE; a first-type bit carried by one of the octets indicates activation or deactivation of a sub-configuration of one CSI report configuration indicated by one of the at least one second-type bit.

[0030] In the above embodiment, the at least one first-type bit and the at least one second-type bit are carried in different octets in the first MAC CE. Respectively. Thus, when decoding the first MAC CE, the terminal may first decode the octet where the at least one second-type bit is located, and then selectively decode the octet carrying the at least one first-type bit according to a decoding result of the at least one second-type bit, to reduce the decoding amount of the terminal and improve a decoding efficiency.

[0031] In combination with some embodiments of the first aspect, in some embodiments, bits of the first MAC CE form N octets, where N is a positive integer greater than or equal to 3; a first octet of the first MAC CE at least indicates a serving cell identity and / or a bandwidth part (BWP) identity; the at least one second-type bit is located in a second octet of the first MAC CE; a first-type bit of the at least one first-type bit is located in an n-th octet of the first MAC CE; where n is a positive integer greater than or equal to 3 and less than or equal to N.

[0032] In the above embodiment, at least one octet is added on the basis of an existing MAC CE, and the at least one newly added octet is used to carry the at least one first-type bit. Thus, when decoding the first MAC CE, the terminal may determine the activated CSI report configuration according to the octet where the at least one second-type bit is located, and determine the octet associated with the activated CSI report configuration among a plurality of octets carrying first-type bits, to decode the first-type bits of the octets, so as to obtain the activation or deactivation of the sub-configuration in the activated CSI report configuration, reduce the decoding amount of the terminal, and improve the decoding efficiency.

[0033] In combination with some embodiments of the first aspect, in some embodiments, identities corresponding to CSI report configurations mapped from a third octet to an N-th octet of the first MAC CE increase progressively; or identities corresponding to CSI report configurations mapped from a third octet to an N-th octet of the first MAC CE decrease progressively.

[0034] In the above embodiment, the identities corresponding to the CSI report configurations mapped from the third octet to the N-th octet of the first MAC CE may present a trend of progressively increasing or decreasing, thus improving a format flexibility of the first MAC CE.

[0035] In combination with some embodiments of the first aspect, in some embodiments, the first MAC CE includes M octets, where M is a positive integer greater than or equal to 2; a first-type bit of the at least one first-type bit is located in an m-th octet of the first MAC CE, where m is greater than or equal to 2 and less than or equal to M; a first-type bit in one octet indicates activation or deactivation of a sub-configuration in one CSI report configuration.

[0036] In the above embodiment, the first MAC CE includes a plurality of octets, and the at least one first-type bit is in a plurality of octets other than the first octet in the first MAC CE. The plurality of octets carrying first-type bits are directly used to, on the one hand, indicate the activation or deactivation of sub-configurations in the CSI report configuration using the first-type bits, and on the other hand, indicate the activation or deactivation of the CSI report configuration corresponding to the octet, without need to carry the second-type bit in the first MAC CE, which reduces the number of bits occupied by the first MAC CE and reduces the signaling overhead.

[0037] In combination with some embodiments of the first aspect, in some embodiments, identities corresponding to CSI report configurations mapped from a second octet to an M-th octet of the first MAC CE increase progressively, or identities corresponding to CSI report configurations mapped from a second octet to an M-th octet of the first MAC CE decrease progressively.

[0038] In the above embodiment, the identities corresponding to the CSI report configurations mapped from the second octet to the M-th octet of the first MAC CE may present a trend of progressively increasing or decreasing, thus improving a format flexibility of the first MAC CE.

[0039] In combination with some embodiments of the first aspect, in some embodiments, one of the at least one second-type bit indicates activation or deactivation of one CSI report configuration; one octet of the first MAC CE includes the at least one first-type bit and one second-type bit; in which a first-type bit adjacent to an n-th second-type bit and located in the same octet as the n-th second-type bit indicates activation or deactivation of a sub-configuration in a CSI report configuration corresponding to the n-th second-type bit.

[0040] In the above embodiment, the at least one first-type bit and the second-type bit are simultaneously carried in one octet of the first MAC CE, the first-type bit adjacent to the second-type bit and located in the same octet as the second-type bit indicates activation or deactivation of the sub-configuration in the CSI report configuration corresponding to the second-type bit. Thus, when decoding the first MAC CE, the terminal may determine whether the CSI report configuration corresponding to the second-type bit is activated according to the second-type bit in one octet. In a case where the CSI report configuration corresponding to the second-type bit is activated, the at least one first-type bit adjacent to the second-type bit is decoded to determine the activation or deactivation of the CSI report configuration corresponding to the second-type bit, thus improving the decoding efficiency of the terminal.

[0041] In combination with some embodiments of the first aspect, in some embodiments, one octet includes two second-type bits; the two second-type bits in the one octet are spaced apart, and one second-type bit corresponds to X first-type bits, where X is a positive integer greater than or equal to 1

[0042] In the above embodiment, one octet in the first MAC CE carries two second-type bits and the two second-type bits are distributed at intervals, the first-type bit adjacent to the second-type bit indicates the activation or deactivation of the sub-configuration in the CSI report configuration indicated by the adjacent second-type bit, thus, on the one hand, effectively improving the decoding efficiency of the terminal, and on the other hand, effectively reducing the number of bits occupied by the first MAC CE in a case of ensuring that the first MAC CE can indicate the activation or deactivation of more sub-configurations in the CSI report configuration.

[0043] In combination with some embodiments of the first aspect, in some embodiments, a logical channel identifier (LC ID) of the first MAC CE is different from an LC ID of a second MAC CE, in which the second MAC CE indicate activation or deactivation of the CSI report configuration.

[0044] In the above embodiment, the first MAC CE and the second MAC CE are distinguished by the LC ID carried in a header of a MAC PDU where the MAC CE is located or a header of a MAC sub-PDU. On the one hand, it is convenient for the terminal to directly determine the type of the MAC CE according to the LC ID, and on the other hand, it does not need to occupy the bits of the MAC CE.

[0045] In combination with some embodiments of the first aspect, in some embodiments, the at least one first-type bit is at least one reserved bit of the first MAC CE.

[0046] In the above embodiment, the activation or deactivation of the reporting of the CSI report with a sub-configuration granularity is realized by the at least one reserved bit in the existing MAC CE, which may realize a finer-grained configuration for the CSI report without modifying the format of the existing MAC CE.

[0047] In combination with some embodiments of the first aspect, in some embodiments, the first MAC CE includes a first octet and a second octet; in which the third-type bit is a reserved bit of the first octet, and the at least one first-type bit is at least one reserved bit of the second octet.

[0048] In the above embodiment, the type of the MAC CE is indicated by the reserved bit in the first octet in the existing MAC CE, and the activation or deactivation of the sub-configuration in the CSI report configuration is indicated by the reserved bit in the second octet in the existing MAC CE, which can not only indicate the type of MAC CE, but also implement a more fine-grained configuration for the CSI report, without modifying the format of the existing MAC CE.

[0097] In some embodiments, for activating or deactivating a MAC CE for SP CSI reporting, as shown in FIG. 1B, FIG. 1B is a schematic diagram of a structure of a MAC CE according to an example embodiment.

[0098] A serving cell identity (ID)indicates an identity of a serving cell for which the MAC CE applies. A length of the field is 5 bits.

[0099] A bandwidth part (BWP) ID indicates an uplink (UL) BWP for which the MAC CE applies as a codepoint of a downlink control information (DCI) bandwidth part indicator field as specified in TS 38.212 [9]. A length of the BWP ID field is 2 bits.

[0100] Si indicates an activation / deactivation status of a semi-persistent CSI report configuration in a CSI report configuration (csi-ReportConfigToAddModList), as specified in TS 38.331 [5].

[0101] S0 refers to a CSI report configuration which includes PUCCH resources for SP CSI reporting in an indicated BWP and has a lowest CSI configuration identify (CSI-ReportConfigId) within a list with a type set to semiPersistentOnPUCCH,

[0102] S1 refers to a report configuration which includes PUCCH resources for SP CSI reporting in the indicated BWP and has a second lowest CSI-ReportConfigId, and so on.

[0103] If the number of report configurations within the list with a type set to semiPersistentOnPUCCH in the indicated BWP is less than i + 1, a MAC entity shall ignore a Si field.

[0104] The Si field is set to 1 to indicate that the corresponding semi-persistent CSI report configuration shall be activated. The Si field is set to 0 to indicate that the corresponding semi-persistent CSI report configuration shall be deactivated.

[0105] FIG. 2 is a schematic diagram illustrating an interaction of a method for processing a CSI report configuration according to an embodiment of the disclosure. As shown in FIG. 2, an embodiment of the present disclosure relates to a method for processing a CSI report configuration, configured in a communication system 100, and the method includes step S2101 and step S2102.

[0106] As step S2101, a network device sends a MAC CE to a terminal.

[0107] In some embodiments, the terminal receives the MAC CE sent by the network device.

[0108] In some embodiments, the network device may include, but is not limited to, an access network device.

[0109] In some embodiments, the terminal may be various types of communication devices. The terminal may be a mobile terminal or a fixed terminal. For example, the terminal may be a mobile phone, a tablet computer, a smart office device, a smart home device, a vehicle-mounted device, and / or an aircraft device.

[0110] In some embodiments, the MAC CE is used to activate or deactivate reporting of a semi-persistent channel state information (SP-CSI) report.

[0111] In some embodiments, the MAC CE is used to activate or deactivate reporting of the SP-CSI report at different configuration granularities.

[0112] In some embodiments, the MAC CE may include one of: a first MAC CE; or a second MAC CE.

[0113] In some embodiments, the first MAC CE is used to activate or deactivate reporting of the CSI report at a granularity of sub-configuration.

[0114] In some embodiments, the second MAC CE is used to activate or deactivate reporting of the CSI report at a granularity of CSI report configuration.

[0115] In some embodiments, a sub-configuration of a CSI report configuration corresponds to a spatial pattern (SD) element and / or transmitting power consumption.

[0116] It should be noted that each CSI report configuration may include a plurality of sub-configurations. Each sub-configuration may be associated with a spatial pattern (spatial pattern, SD) and / or a plurality of power consumption (power) modes.

[0117] The first MAC CE may activate the reporting of the CSI report at the granularity of sub-configuration, that is, the first MAC CE may activate a part of sub-configurations in the CSI report configuration, and deactivate another part of the sub-configurations in the CSI report configuration. The second MAC CE may activate reporting of the CSI report at the granularity of CSI report configuration, that is, the second MAC CE may activate or deactivate only the entire CSI report configuration (all of the sub-configurations in the CSI report configuration). The two different types of MAC CEs have different configuration granularities for activating or deactivating the CSI report.

[0118] In order to facilitate the terminal to determine whether the received MAC CE is the first MAC CE or the second MAC CE, in some embodiments, the MAC CE includes: a third-type bit.

[0119] In some embodiments, a first bit value of the third-type bit indicates that the MAC CE is the first MAC CE.

[0120] In some embodiments, a second bit value of the third-type bit indicates that the MAC CE is the second MAC CE.

[0121] It should be noted that the first MAC CE and the second MAC CE may be distinguished by different bit values of the third-type bit.

[0122] In some embodiments, the third-type bit may be a reserved bit in the MAC CE.

[0123] It is worth noting that the reserved bit in the MAC CE may be directly used to distinguish the first MAC CE from the second MAC CE through different bit values of the reserved bit. In this embodiment, the third-type bit may be carried in the MAC CE as a body content of the MAC CE.

[0124] In some other embodiments, the first MAC CE and the second MAC CE may be distinguished based on a logical channel identifier (LC ID) of the MAC CE.

[0125] In some embodiments, an LC ID of the first MAC CE is different from an LC ID of the second MAC CE.

[0126] It should be noted that a header of a MAC protocol data unit (PDU) where the MAC CE is located or a header of a MAC sub-PDU may include an LC ID field, and an LC ID carried in an LC ID field may be used to indicate whether the MAC CE is the first MAC CE or the second MAC CE.

[0127] In some embodiments, the first MAC CE and the second MAC CE may be indicated respectively based on two different reserved codepoints in the LC ID field.

[0128] It should be noted that the LC ID field may include a plurality of bits. Illustratively, the LC ID field may include 8 bits, and the 8 bits may have 64 codepoints. For example, 37-42 and 47 codepoints among the 64 codepoints are reserved codepoints. In embodiments of the present disclosure, these reserved codepoints may be used to indicate the first MAC CE and the second MAC CE.

[0129] In some embodiments, the first MAC CE may include: at least one first-type bit, indicating activation or deactivation of the sub-configuration.

[0130] In some embodiments, the at least one first-type bit is a bitmap, one bit in the bitmap indicates activation or deactivation of one sub-configurations.

[0131] It should be noted that at least one first-type bit may indicate the activation or deactivation of at least one sub-configuration in the CSI report configuration by means of the bitmap. Each bit in the bitmap corresponds to one sub-configuration, and different bits carry specific bit values to indicate the activation or deactivation of the sub-configurations corresponding to the bits.

[0132] It is worth noting that a method of indicating the activation or deactivation of the sub-configuration based on the bitmap may effectively reduce a decoding complexity of the at least one first-type bit in the first MAC CE. However, since one bit in the bitmap corresponds to one sub-configuration, the at least one first-type bit in the first MAC CE may indicate the number of activated or deactivated sub-configurations which is limited by the number of first-type bits in the first MAC CE.

[0133] For example, the first MAC CE includes 4 first-type bits, and the first MAC CE may only indicate activation or deactivation of 4 sub-configurations.

[0134] In some embodiments, the at least one first-type bit is joint indication information, in which one sequence value of the at least one first-type bit indicates a combination relationship of activation or deactivation of a plurality of sub-configurations, and the one sequence value is determined based on at least one bit value of the at least one first-type bit.

[0135] It should be noted that the at least one first-type bit in the first MAC CE forms an indication sequence. Different sequence values of the indication sequence are used to indicate different combination relationships of activation or deactivation of the plurality of sub-configurations in the CSI report configuration.

[0136] In some embodiments, a mapping relationship between different sequence values of the at least one first-type bit and different combination relationships of activation or deactivation of the plurality of sub-configurations in the CSI report configuration may be pre-configured. Thus, the one sequence value formed by the at least one first-type bit is used to indicate the combination relationship of activation or deactivation of the plurality of sub-configurations in the CSI report configuration.

[0137] It is worth noting that the method for indicating the activation or deactivation of the sub-configuration based on the joint indication information may effectively increase the number of different situations of activation or deactivation of the plurality of sub-configurations that can be indicated by the at least one first-type bit. By using a smaller number of first-type bits to indicate the combination relationship of activation or deactivation of more sub-configurations, which may effectively reduce the number of bits occupied by the first MAC CE.

[0138] For example, the first MAC CE includes 4 first-type bits, and the 4 first-type bits form an indication sequence with 16 different sequence values. Thus, different sequence values of the indication sequence are used to indicate different combination relationships of activation or deactivation of all of the sub-configurations in the CSI report configuration.

[0139] In some embodiments, the first MAC CE further includes: at least one second-type bit, indicating activation or deactivation of the CSI report configuration. The first-type bit is used to indicate activation or deactivation of a sub-configuration in an activated CSI report configuration.

[0140] It should be noted that different bit values of the second-type bit may indicate the activation or deactivation of the CSI report configuration corresponding to the second-type bit. Further, different bit values of the first-type bit may indicate the activation or deactivation of the sub-configuration corresponding to the first-type bit in the activated CSI report configuration.

[0141] In some embodiments, the second-type bit may be S bits in an existing MAC CE.

[0142] It should be noted that the S bits in the existing MAC CE may be 4 bits, namely S0 to S3. It may be noted that S0 to S3 correspond to different CSI report configurations respectively.

[0143] The first MAC CE may have a plurality of different optional structures, and several optional embodiments are provided below.Optional embodiment one:

[0144] In some embodiments, the first MAC CE includes a first octet and a second octet. The third-type bit is a reserved bit of the first octet, and the at least one first-type bit is at least one reserved bit of the second octet.

[0145] It should be noted that the first MAC CE as shown in the above embodiment may directly use the reserved bit in the existing MAC CE. Specifically, the reserved bit in the first octet is used to carry the third-type bit. The at least one reserved bit in the second octet is used to carry the at least one first-type bit. In this way, the reserved bit in the second octet in the existing MAC CE may be directly used, without modifying the structure of the existing MAC CE, to realize the activation or deactivation of the reporting of the CSI report at the granularity of sub-configuration.

[0146] In some embodiments, the second octet further includes: at least one second-type bit.

[0147] In some embodiments, the at least one second-type bit indicates activation or deactivation of the CSI report configuration.

[0148] The at least one first-type bit in the second octet indicates activation or deactivation of the sub-configuration in an activated CSI report configuration indicated by the at least one second-type bit.

[0149] In some embodiments, the first octet further indicates a serving cell identity (ID) and / or a bandwidth part (BWP) identity (ID).

[0150] In some embodiments, the first octet further includes at least one of: a first information field carries the serving cell ID; or a second information field carries the BWP ID.

[0151] It should be noted that the serving cell ID indicates an identity of the serving cell to which the first MAC CE applies, and a length of the first information field may be 5 bits. The BWP ID indicates an identity of an uplink BWP to which the first MAC CE applies. A length of the second information field may be 2 bits.

[0152] In some embodiments, the first octet of the first MAC CE may carry one third-type bit; the second octet may carry four second-type bits and four first-type bits.

[0153] It is worth noting that when a bit value of the third-type bit is 1, it indicates that the MAC CE is the first MAC CE. When a bit value of the third-type bit is 0, it indicates that the MAC CE is the second MAC CE.

[0154] In some embodiments, the four first-type bits in the second octet indicate at least one of: activation or deactivation of sub-configurations in all of activated CSI report configurations indicated by the 4 four second-type bits in the second octet; or activation or deactivation of a sub-configuration in a reference CSI report configuration.

[0155] It should be noted that the reference CSI report configuration may be determined based on a predefined manner. For example, the reference CSI report configuration may be a CSI report configuration corresponding to a minimum CSI configuration identify in a CSI report configuration set.

[0156] In some embodiments, a size of the first MAC CE is 16 bits.Optional embodiment two:

[0157] In some embodiments, the at least one first-type bit is at least one reserved bit of the first MAC CE.

[0158] It should be noted that an embodiment of the present disclosure directly uses the at least one reserved bit in the existing MAC CE to carry the at least one first-type bit to indicate the activation or deactivation of the sub-configuration. In this way, the activation or deactivation of the reporting of the CSI report at the granularity of sub-configuration may be achieved without modifying the structure of the existing MAC CE.

[0159] In some embodiments, the first MAC CE includes: a first octet and a second octet. The at least one first-type bit is a reserved bit in the first octet and the second octet.

[0160] It is worth noting that the reserved bit in the first MAC CE in this embodiment is used to carry the first-type bit. That is, the first MAC CE does not include the third-type bit.

[0161] In order to distinguish the first MAC CE from the second MAC CE, in some embodiments, a header of a MAC PDU or a header of a MAC sub-PDU where the first MAC CE is located may include: an LC ID field. The LC ID field carries an LC ID corresponding to the first MAC CE.

[0162] In some other embodiments, the first MAC CE and the second MAC CE may be distinguished according to a bit value of the reserved bit in the MAC CE.

[0163] It should be noted that, whether reserved bits of the MAC CE are used to carry the first-type bits may be determined based on whether the bit values of all of the reserved bits of the MAC CE are preset bit values, and then whether the MAC CE is the first MAC CE may be determined.

[0164] For example, if the bit values of all of the reserved bits in the MAC CE are 0, it indicates that the MAC CE is the second MAC CE.

[0165] In some embodiments, the second octet further includes: at least one second-type bit.

[0166] In some embodiments, at least one second-type bit indicates an activated or deactivated CSI report configuration. The at least one first-type bit in the second octet indicates activation or deactivation of a sub-configuration in an activated CSI report configuration indicated by the second-type bit.

[0167] In some embodiments, the first octet is further used to indicate a serving cell identity and / or a BWP identity.

[0168] In some embodiments, the first octet further includes at least one of: a first information field carries the serving cell ID; or a second information field carries the BWP ID.

[0169] It should be noted that the serving cell ID indicates an identity of the serving cell to which the first MAC CE applies, and a length of the first information field may be 5 bits. The BWP ID indicates an identity of an uplink BWP to which the first MAC CE applies. A length of the second information field may be 2 bits.

[0170] In some embodiments, the first octet of the first MAC CE may carry one first-type bit; the second octet may carry four second-type bits and four first-type bits.

[0171] In some embodiments, the four first-type bits in the second octet indicate at least one of: activation or deactivation of sub-configurations in all of activated CSI report configurations indicated by the 4 four second-type bits in the second octet; or activation or deactivation of a sub-configuration in a reference CSI report configuration.

[0172] It should be noted that the reference CSI report configuration may be determined based on a predefined manner. For example, the reference CSI report configuration may be a CSI report configuration corresponding to a minimum CSI configuration identify in a CSI report configuration set.

[0173] In some embodiments, a size of the first MAC CE is 16 bits.Optional embodiment three:

[0174] In some embodiments, the at least one first-type bit and the at least one second-type bit are located in different octets of the first MAC CE. A first-type bit carried by one of the octets indicates activation or deactivation of a sub-configuration of one CSI report configuration indicated by one of the at least one second-type bit

[0175] It should be noted that, the first MAC CE in this embodiment adds at least one octet for carrying at least one first-type bit on the basis of the existing MAC CE. The first-type bit carried by one octet corresponds to one CSI report configuration indicated by one second-type bit, to indicate the activation or deactivation of the sub-configuration within the corresponding CSI report configuration.

[0176] In some embodiments, bits of the first MAC CE form N octets, where N is a positive integer greater than or equal to 3; a first octet of the first MAC CE at least indicates a serving cell identity and / or a bandwidth part (BWP) identity; the at least one second-type bit is in a second octet of the first MAC CE; and a first-type bit of the at least one first-type bit is in an n-th octet of the first MAC CE; where n is a positive integer greater than or equal to 3 and less than or equal to N.

[0177] It is worth noting that the first MAC CE in the present disclosure retains the structure of the existing MAC CE, that is, the first octet and the second octet in the existing MAC CE are retained. The activation or deactivation of the sub-configuration in one CSI report configuration indicated by one second-type bit is indicated through the newly added first-type bit in each octet.

[0178] In some embodiments, identities corresponding to CSI report configurations mapped from a third octet to an N-th octet of the first MAC CE increase progressively.

[0179] It may be understood that a first-type bit in the third octet is used to activate or deactivate a plurality of sub-configurations in a CSI report configuration indicated by the second-type bit corresponding to a minimum CSI configuration identify. A first-type bit in the N-th octet is used to activate or deactivate a plurality of sub-configurations in a CSI report configuration indicated by the second-type bit corresponding to a maximum CSI configuration identify.

[0180] In some other embodiments, identities corresponding to CSI report configurations mapped from a third octet to an N-th octet of the first MAC CE decrease progressively.

[0181] It may be understood that a first-type bit in the third octet is used to activate or deactivate a plurality of sub-configurations in a CSI report configuration indicated by the second-type bit corresponding to the maximum CSI configuration identify. A first-type bit in the N-th octet is used to activate or deactivate a plurality of sub-configurations in a CSI report configuration indicated by the second-type bit corresponding to the minimum CSI configuration identify.

[0182] In some embodiments, a first-type bit in one octet corresponds to a plurality of sub-configurations in one activated CSI report configuration indicated by the second-type bit; or a first-type bit in one octet corresponds to a plurality of sub-configurations in one CSI report configuration in a CSI report configuration set.

[0183] It is worth noting that the number of newly added octets in the first MAC CE may be determined according to the number of activated CSI report configurations indicated by the at least one second-type bit in the second octet. It may be understood that for each activated CSI report configuration, there is a corresponding octet carrying the first-type bit. The first-type bits in one octet indicates the activation or deactivation of the sub-configuration in the corresponding activated CSI report configuration.

[0184] Or, the number of newly added octets in the first MAC CE may be determined according to the number of CSI report configurations included in the CSI report configuration set. It is understandable that, for each CSI report configuration in the CSI report configuration set, there is one corresponding octet carrying the first-type bit. That is, a deactivated CSI report configuration also corresponds to one octet carrying the first-type bit. The first-type bit in one octet indicates the activation or deactivation of the sub-configuration in the corresponding CSI report configuration.

[0185] In some embodiments, the first octet further includes at least one of: a first information field carries the serving cell ID; or a second information field carries the BWP ID.

[0186] It should be noted that the serving cell ID indicates an identity of the serving cell to which the first MAC CE applies, and a length of the first information field may be 5 bits. The BWP ID indicates an identity of an uplink BWP to which the first MAC CE applies. A length of the second information field may be 2 bits.

[0187] In some embodiments, the first MAC CE may be a MAC CE with a variable size.

[0188] In some embodiments, a size of the first MAC CE is N*8 bits.

[0189] It may be noted that the size of the first MAC CE in this embodiment may be determined by the number of octets included in the first MAC CE.Optional embodiment four:

[0190] In some embodiments, the first MAC CE includes M octets, where M is a positive integer greater than or equal to 2.

[0191] A first-type bit of the at least one first-type bit is in an m-th octet of the first MAC CE, where m is greater than or equal to 2 and less than or equal to M.

[0192] A first-type bit in one octet indicates activation or deactivation of a sub-configuration in one CSI report configuration.

[0193] It should be noted that, compared with the first MAC CE shown in optional embodiment three, the first MAC CE of this embodiment of the present disclosure does not include an octet carrying the second-type bit. That is, the first MAC CE in this embodiment of the present disclosure does not carry the second- type bit.

[0194] In some embodiments, identities corresponding to CSI report configurations mapped from a second octet to an M-th octet of the first MAC CE increase progressively.

[0195] It may be noted that the first-type bit in the second octet is used to activate or deactivate a plurality of sub-configurations in a CSI report configuration corresponding to a minimum CSI configuration identify in a CSI report configuration set. The first-type bit in the M-th octet is used to activate or deactivate a plurality of sub-configurations in a CSI report configuration corresponding to a maximum CSI configuration identify in the CSI report configuration set.

[0196] In some embodiments, identities corresponding to CSI report configurations mapped from a second octet to an M-th octet of the first MAC CE decrease progressively.

[0197] It may be noted that the first-type bit in the second octet is used to activate or deactivate a plurality of sub-configurations in a CSI report configuration corresponding to the maximum CSI configuration identify in a CSI report configuration set. The first-type bit in the M-th octet is used to activate or deactivate a plurality of sub-configurations in a CSI report configuration corresponding to the minimum CSI configuration identify in the CSI report configuration set.

[0198] In some embodiments, the first octet in the first MAC CE may at least indicate a serving cell identify and / or a BWP identify.

[0199] In some embodiments, the first octet further includes at least one of: a first information field carries the serving cell ID; or a second information field carries the BWP ID.

[0200] It should be noted that the serving cell ID indicates an identity of the serving cell to which the first MAC CE applies, and a length of the first information field may be 5 bits. The BWP ID indicates an identity of an uplink BWP to which the first MAC CE applies. A length of the second information field may be 2 bits.

[0201] In some embodiments, the third-type bit is a reserved bit of the first octet.

[0202] It may be noted that the first MAC CE and the second MAC CE are distinguished by directly using different bit values of the third-type bit.

[0203] In some embodiments, the first MAC CE may be a MAC CE with a variable size.

[0204] In some embodiments, a size of the first MAC CE is M*8 bits.

[0205] It may be noted that the size of the first MAC CE in this embodiment may be determined by the number of octets included in the first MAC CE.

[0206] In some embodiments, such a first MAC CE may not include the second-type bit.Optional embodiment five:

[0207] In some embodiments, one of the at least one second-type bit indicates activation or deactivation of one CSI report configuration.

[0208] One octet of the first MAC CE includes the at least one first-type bit and one second-type bit.

[0209] A first-type bit adjacent to an n-th second-type bit and located in the same octet as the n-th second-type bit indicates activation or deactivation of a sub-configuration in a CSI report configuration corresponding to the n-th second-type bit.

[0210] It should be noted that the first MAC CE shown in this embodiment of the present disclosure may carry the first-type bit and the second-type bit in the same octet, and the first-type bit adjacent to the second-type bit in the same octet is used to indicate the activation or deactivation of the sub-configuration in the activated CSI report configuration indicated by the second-type bit.

[0211] In some embodiments, one octet includes two second-type bits.

[0212] The two second-type bits in the one octet are spaced apart, and one second-type bit corresponds to X first-type bits, where X is a positive integer greater than or equal to 1 and less than or equal to 3.

[0213] It may be understood that the two second-type bits in the one octet indicate the activation or deactivation of different CSI report configurations respectively. The first-type bit adjacent to one second-type bit and located in the same octet as the second-type bit indicates the activation or deactivation of the sub-configuration in one activated CSI report configuration indicated by the adjacent second-type bit, and the first-type bit adjacent to another second-type bit and located in the same octet as another second-type bit indicates the activation or deactivation of the sub-configuration in one activated CSI report configuration indicated by the adjacent second-type bit.

[0214] In some embodiments, one octet includes two second-type bits.

[0215] The two second-type bits in the one octet are spaced apart, and one second-type bit corresponds to three first-type bits.

[0216] In some embodiments, the first octet in the first MAC CE may at least indicate a serving cell identify and / or a BWP identify.

[0217] In some embodiments, the first octet further includes at least one of: a first information field carries the serving cell ID; or a second information field carries the BWP ID.

[0218] It should be noted that the serving cell ID indicates an identity of the serving cell to which the first MAC CE applies, and a length of the first information field may be 5 bits. The BWP ID indicates an identity of an uplink BWP to which the first MAC CE applies. A length of the second information field may be 2 bits.

[0219] In some embodiments, the third-type bit is a reserved bit of the first octet.

[0220] It may be noted that the first MAC CE and the second MAC CE are distinguished by directly using different bit values of the third-type bit.

[0221] In some embodiments, the first MAC CE may be a MAC CE with a variable size.

[0222] In some embodiments, a size of the first MAC CE is M*8 bits.

[0223] It may be noted that the size of the first MAC CE in this embodiment may be determined by the number of octets included in the first MAC CE.

[0224] In some embodiments, the network device may determine a format of the first MAC CE sent to the terminal based on a protocol agreement.

[0225] In some embodiments, the network device may send second information to the terminal, in which the second information indicates the format of the first MAC CE.

[0226] It may be noted that the network device may determine the format of the first MAC CE sent to the terminal by itself, and inform the terminal through the second information so that the terminal may decode first MAC CE.

[0227] In some embodiments, the terminal may send third information to the network device, in which the third information indicates the format of the first MAC CE.

[0228] It may be noted that the terminal may send the third information to the network device to inform the network device of the format of the first MAC CE that the terminal expects to use. The network device may determine the format of the first MAC CE based on the third information.

[0229] It is worth noting that the format of the first MAC CE finally determined by the network device may be the same as or different from the format of the first MAC CE that the terminal expects to use. In order to achieve information alignment, the network device may send the second information to the terminal after determining the format of the first MAC CE.

[0230] Step S2102: The terminal determines activation or deactivation of a sub-configuration of the CSI report configuration.

[0231] In some embodiments, the terminal determines activation or deactivation of the sub-configuration in the CSI report configuration based on a received MAC CE.

[0232] In some embodiments, the terminal determines activation or deactivation of the sub-configuration in the CSI report configuration according to a received first MAC CE.

[0233] In some embodiments, the terminal may determine whether the received MAC CE is the first MAC CE based on the third-type bits in the MAC CE.

[0234] It may be noted that since different bit values of the third-type bit may be used to distinguish the first MAC CE and the second MAC CE, the terminal may decode the received MAC CE and determine whether the received MAC CE is the first MAC CE or the second MAC CE based on a bit value of the third-type bit carried in the MAC CE.

[0235] In some embodiments, the terminal may determine whether the received MAC CE is the first MAC CE based on an LC ID carried in a header of a MAC PDU where the MAC CE is located or a header of a MAC sub-PDU.

[0236] It should be noted that, since an LC ID of the first MAC CE is different from an LC ID of the second MAC CE, the terminal may obtain the LC ID carried in the header of the MAC PDU where the MAC CE is located or the header of the MAC sub-PDU, and determine whether the received MAC CE is the first MAC CE.

[0237] In some embodiments, the terminal may determine activation or deactivation of the sub-configuration of the CSI report configuration based on the at least one first-type bit in the first MAC CE.

[0238] In some embodiments, an identifier of an activated sub-configuration indicated by the first-type bit exceeds an identifier range of sub-configuration included in the CSI report configuration, and the terminal may ignore the first-type bit.

[0239] In some embodiments, the terminal may determine the activated or deactivated CSI report configuration based on the at least one second type bit in the first MAC CE, and determine the activation or deactivation of the sub-configuration in the activated CSI report configuration based on the at least one first type bit.

[0240] In some embodiments, the terminal determines the format of the received first MAC CE.

[0241] It should be noted that the first MAC CE may have different optional formats, and decoding information of the first MAC CE in different formats may indicate different contents. Therefore, the terminal needs to first determine the format of the received first MAC CE.

[0242] In some embodiments, the terminal may determine the format of the first MAC CE according to a protocol agreement.

[0243] In some embodiments, the terminal may determine the format of the first MAC CE according to the second information sent by the network device.

[0244] For a first optional format of the first MAC CE: In some embodiments, the terminal may determine whether the MAC CE is the first MAC CE based on a reserved bit in the first octet of the MAC CE.

[0245] In some embodiments, the terminal may determine activation or deactivation of the sub-configuration in the CSI report configuration based on the reserved bit of the second octet in the first MAC CE.

[0246] In some embodiments, the terminal may determine the activated CSI report configuration based on the second-type bit of the second octet in the first MAC CE, and determine the activation or deactivation of the sub-configuration in the activated CSI report configuration based on the reserved bit of the second octet in the first MAC CE.

[0247] It should be noted that, the first MAC CE in the first optional format may indicate to the terminal the activation or deactivation of the sub-configuration in the activated CSI report configuration without changing the existing format of the MAC CE.

[0248] For a second optional format of the first MAC CE: In some embodiments, the terminal may determine whether the MAC CE is the first MAC CE based on the LC ID carried in the header of the MAC PDU where the MAC CE is located or the header of the MAC sub-PDU.

[0249] In some embodiments, the terminal may determine activation or deactivation of the sub-configuration in the CSI report configuration based on all of reserved bits in the first MAC CE.

[0250] In some embodiments, the terminal may determine the activated CSI report configuration based on the second-type bit of the second octet in the first MAC CE, and determine the activation or deactivation of the sub-configuration in the activated CSI report configuration based on all of the reserved bits in the first MAC CE.

[0251] It should be noted that the first MAC CE in the second optional format may indicate to the terminal the activation or deactivation of the sub-configuration in the activated CSI report configuration without changing the existing format of the MAC CE.

[0252] For a third optional format of the first MAC CE: In some embodiments, the terminal may determine whether the MAC CE is the first MAC CE based on a reserved bit in a first octet of the MAC CE.

[0253] In some embodiments, the terminal may determine an identifier corresponding to an activated CSI report configuration based on the second-type bit of the second octet in the first MAC CE, and determine the corresponding octet based on the identifier corresponding to the activated CSI report configuration, and determine the activation or deactivation of the sub-configuration in the activated CSI report configuration based on the first-type bit in the corresponding octet.

[0254] It should be noted that the first MAC CE in the third optional format can not only indicate to the terminal the activation or deactivation of the sub-configuration in the activated CSI report configuration, but also reduce the decoding amount of the terminal.

[0255] For s fourth optional format of the first MAC CE: In some embodiments, the terminal may determine whether the MAC CE is the first MAC CE based on a reserved bit in the first octet of the MAC CE.

[0256] In some embodiments, the terminal may determine activation or deactivation of a sub-configuration in a CSI report configuration corresponding to the m-th octet based on the first-type bit in the m-th octet in the first MAC CE.

[0257] It should be noted that the first MAC CE in the fourth optional format, without carrying the second-type bit, may be able to indicate to the terminal the activated CSI report configuration and the activation or deactivation of the sub-configuration in the activated CSI report configuration.

[0258] For a fifth optional format of the first MAC CE: In some embodiments, the terminal may determine whether the MAC CE is the first MAC CE based on a reserved bit in a first octet of the MAC CE.

[0259] In some embodiments, the terminal may determine the activated CSI report configuration based on the second-type bit in one octet, and determine the activation or deactivation of the sub-configuration in the activated CSI report configuration based on the first-type bit adjacent to the second-type bit indicating the activated CSI report configuration in the same octet.

[0260] It should be noted that the first MAC CE in the fifth optional format may not only indicate to the terminal the activation or deactivation of the sub-configuration in the activated CSI report configuration, but also reduce the decoding amount of the terminal.

[0261] In some embodiments, the terminal may perform a corresponding measurement based on an activated sub-configuration in the CSI report configuration.

[0262] It should be noted that the sub-configuration of the CSI report configuration corresponds to a spatial pattern (SD) element and / or the transmitting power consumption. Compared with a manner by which the terminal performs the measurement based on the CSI report configuration, in embodiments of the present disclosure, the terminal only performs the measurement related to the partially activated sub-configuration in the CSI report configuration, which may effectively reduce the measurement power consumption of the terminal.

[0263] Furthermore, a measurement result obtained by the terminal based on the measurement related to the partially activated sub-configuration in the CSI report configuration may be reduced accordingly, thus reducing resources required for reporting of the CSI report.

[0264] In some embodiments, the terminal may receive a second MAC CE sent by the network device.

[0265] In some embodiments, the terminal determines to activate or deactivate the CSI configuration report based on the second MAC CE.

For example, step S2101 may be implemented as an independent embodiment. For example, step S2103 may be implemented as an independent embodiment, but is not limited thereto.

[0267] In some embodiments, step S2102 is optional, and one or more of these steps may be omitted or replaced in different embodiments. It is noted that, when the network device sends the second MAC CE, since the second MAC CE can only indicate the activation of the CSI report configuration, the terminal does not need to activate or deactivate the sub-configuration in the CSI report configuration.

[0316] FIG. 5 is a schematic diagram of an interaction of a method for processing a CSI report configuration according to an embodiment. As shown in FIG. 5, an embodiment of the present disclosure relates to method for processing a CSI report configuration, and is performed by a terminal in a non-connected state. The method includes step S5101.

[0317] Step S5101, a network device sends a MAC CE to the terminal.

[0318] In some embodiments, the MAC CE includes a first MAC CE, the first MAC CE carries first information.

[0319] In some embodiments, the first information indicates activation or deactivation of a sub-configuration of a CSI report configuration.

[0320] In some embodiments, the above method may include the methods of embodiments on the communication system side, the terminal side, the network device side, etc., which is not be repeated here.

[0321] In a Rel-18 NES scenario, in order to reduce power overhead of a network device, the network device may dynamically reduce the number of spatial elements or transmitting power corresponding to transmission of downlink data based on a dynamic change in a transmission load, thus reducing network energy overhead. Taking into account a spatial adaptation (SD) pattern for dynamic adjustment of the spatial elements or the transmitting power, Rel-18 defines CSI reporting with a sub-configuration as a granularity. For the same CSI report config, the CSI report configuration may include L sub-configurations, each of which is associated with a specific spatial pattern (SD) and / or a plurality of power consumption (power) patterns.

[0322] In order to improve a reporting efficiency of a terminal and reduce the corresponding reporting overhead, for the configured L sub-configurations, a base station may activate / deactivate N out of the L sub-configurations for report via relevant signaling. For SP-CSI reporting, activation / deactivation may be performed via a MAC CE. However, in the existing mechanism, the MAC CE only activates / deactivates reporting with CSI report config as the granularity. After the introduction of reporting with the sub-configuration as the granularity, how to activate / deactivate N out of the L sub-configurations for report is still under further discussion.

[0323] The technical problem solved by embodiments of the present disclosure, that is, a core idea of the present disclosure, as described in the background, is to design signaling to indicate an activated / deactivated report sub-configuration in a condition that one CSI report config includes a plurality of report sub-configurations, to improve an efficiency and an accuracy of CSI measurement reporting and achieve consistent understanding between the terminal and the base station.

[0324] In the condition that the one CSI report config includes the plurality of report sub-configurations, the terminal receives indication signaling, determines the activated report sub-configuration, and performs the corresponding CSI report.

[0325] A reserved bit (e.g., R) field of an existing MAC CE is refarmed, or a new field, such as Ni, is introduced, to indicate an activation / deactivation status of the corresponding sub-configuration in a bitmap manner.

[0326] N0 corresponds to a sub-configuration with the smallest sub-configuration identity (sub-configuration id) or the smallest position index in the CSI report config. Ni corresponds to a sub-configuration with the (i+1)th smallest sub-configuration id or the (i+1)th smallest position index in the CSI report configuration.

[0327] In a case where Ni is 0, it indicates that the corresponding sub-configuration is deactivated. In a case where Ni is 1, it indicates that the corresponding sub-configuration is activated.

[0328] If a MAC CE is enhanced based on the existing MAC CE, the terminal determines an indication function of the MAC CE based on an R field of Oct 1. That is, if the indication is 0, the MAC CE is a legacy MAC CE, which indicates activation / deactivation of the CSI report config, and if the indication is 1, the MAC CE indicates the activation / deactivation of the CSI report sub-configuration.

[0329] If a fixed size of the MAC CE is N bits, N is greater than or equal to 16, or corresponds to a variable size.

[0330] In the condition that the one CSI report config includes the plurality of report sub-configurations, the base station determines an activated report sub-configuration, transmits a corresponding indication signaling, and receives a corresponding CSI report result.

[0331] A reserved bit (e.g., R) field of an existing MAC CE is refarmed, or a new field, such as Ni, is introduced, to indicate an activation / deactivation status of the corresponding sub-configuration in a bitmap manner.

[0332] N0 corresponds to a sub-configuration with the smallest sub-configuration identity (sub-configuration id) or the smallest position index in the CSI report config. Ni corresponds to a sub-configuration with the (i+1)th smallest sub-configuration id or the (i+1)th smallest position index in the CSI report configuration.

[0333] In a case where Ni is 0, it indicates that the corresponding sub-configuration is deactivated. In a case where Ni is 1, it indicates that the corresponding sub-configuration is activated.

[0334] If a MAC CE is enhanced based on the existing MAC CE, the terminal determines an indication function of the MAC CE based on an R field of Oct 1. That is, if the indication is 0, the MAC CE is a legacy MAC CE, which indicates activation / deactivation of the CSI report config, and if the indication is 1, the MAC CE indicates the activation / deactivation of the CSI report sub-configuration.

[0335] If a fixed size of the MAC CE is N bits, N is greater than or equal to 16, or corresponds to a variable size.

[0336] The following describes a specific implementation of the present disclosure from the perspective of a terminal and a base station.

[0337] Assumed that the terminal is a terminal supporting an NES feature. To support measurement reporting of a plurality of spatial patterns (spatial pattern, SD) and / or a plurality of power consumption (power) standards, NES supports sub-CSI report that a plurality of sub-configurations are defined for the same CSI report config. Compared with the existing mechanism, in which one CSI report config corresponds to one CSI, for Rel-18 NES, one CSI report config corresponds to the plurality of sub-configurations, and each sub-configuration corresponds to one sub-CSI report, which may effectively improve dynamic CSI measurement reporting performance.

[0338] In a case of configuring the plurality of sub-configurations, embodiments of the present disclosure mainly design corresponding MAC CE indication signaling, based on the existing MAC CE (the existing MAC CE is described in the background), to indicate activation / deactivation of the corresponding sub-configuration, and the specific indication method is described as follows.

[0339] Implementation 1: an existing reserved bit, such as "R", is refarmed, to indicate an activation status of a corresponding sub-configuration. It should be noted that the MAC CE indication signaling shown in Implementation 1 may correspond to the MAC CE in the first format and / or the second format of the present disclosure.

[0340] As shown in FIG. 6A and FIG. 6B, FIG. 6A is a schematic diagram of a structure of a MAC CE in a first format according to an embodiment, and FIG. 6B is a schematic diagram of a structure of a MAC CE in a second format according to an embodiment.

[0341] N0 corresponds to a sub-configuration with the smallest sub-configuration identity (sub-configuration id) or the smallest position index in the CSI report config. Ni corresponds to a sub-configuration with the (i+1)th smallest sub-configuration id or the (i+1)th smallest position index in the CSI report configuration.

[0342] In a case where Ni is 0, it indicates that the corresponding sub-configuration is deactivated. In a case where Ni is 1, it indicates that the corresponding sub-configuration is activated.

[0343] Ni may indicate activation or deactivation of a corresponding sub-configuration in all activated CSI report configurations indicated by S0, S1, ..., S3; or, Ni may indicate activation or deactivation of a corresponding sub-configuration in a reference CSI report configuration. In an example, the reference CSI report configuration is determined based on a predefined manner, for example, the CSI report configuration corresponding to the smallest id.

[0344] If an index of the corresponding sub-configuration indicated by Ni exceeds an index range of the sub-configuration included in the all activated CSI report configurations indicated by S0, S1, ..., S3 or the reference CSI report configuration, the terminal ignores the corresponding sub-configuration. The CSI report configuration is configured based on the CSI-ReportConfig.

[0345] If a MAC CE is enhanced based on the existing MAC CE, the terminal determines an indication function of the MAC CE based on an R field of Oct 1. That is, if the indication is 0, the MAC CE is a legacy MAC CE, which indicates activation / deactivation of the CSI report config, and if the indication is 1, the MAC CE indicates the activation / deactivation of the CSI report sub-configuration.
